Restore AST 'pty' pseudoterminal command (re: reboot)

Browse source

This enables the tests/pty.sh regression tests for the interactive
shell to work. I've managed to restore these without restoring
nmake (which would cause unresolved build failures). It involved
hand-editing the Mamfile originally generated by nmake.

src/cmd/builtin/Makefile:
- Restored. Even though nmake is not installed, apparently mamake
  still needs the Makefile for the 'install' target to work. This
  will probably need editing if nmake is ever restored.

src/cmd/builtin/Mamfile:
- Restored and edited by hand to remove the commands to build all
  the utilities except pty, as well as all test targets (pty has no
  test). Most of this was systematically deleting blocks delimited
  by 'make FOO' and 'done FOO generated' until the build stopped
  failing -- a task made so much easier by the build now failing
  gracefully on error (see d0dfb37c). To see the diff, do:
	git diff cc1f2bf8 src/cmd/builtin/Mamfile

src/cmd/builtin/RELEASE:
- Restored for completeness' sake with all non-pty entries removed.

src/cmd/builtin/features/pty,
src/cmd/builtin/pty.c:
- Restored.
